WATER-HEATING DEVICE.

Specification of Letters Patent.

Application filed November 18, 1915. Serial No. 62,218.

To all whom it may concern.-

Be it known that I, ALBERT B. CLAY, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Water-Heating Devices, of which the following is a specificatio This invention relates to a water heating device which is adapted to be attached to a feed pipe of a range boiler. In its preferred form the device preferably comprises a sleeve having an inside diameter greater than the outside diameter of the pipe to which it is to be attached. The sleeve is the feed pipe and comprises two sections which are joined together, suitable packing being provided in order to prevent leakage ofthe heating medium.

A further feature of the invention resides in so constructing the device that it may be readily drained when placed in a horizontal position on the feed pipe in order to prevent flooding of a suitable air discharge opening which is provided in the sleeve.

' In'the accompanying drawings, Figure 1 is a side view partly in section of the device as applied to a feed pipe of a range boiler; Fig. 2 is the top view partly in section; Fig. 3 is a cross section on the line 3-3, Fig. 1.

Referring to the drawings in detail, A represents a feed pipe of a range boiler. As shown, the device is preferably constructed to use steam as a heating medium and it comprises a sleeve B which is split longitudinally of the feed pipe A, such as at C, in order to produce two sections D and E. These sections are adapted to be joined together by means, such as the bolts F, which are carried by the ears G on the two abutting sections. In order to prevent leakage at the abutting faces of each. section, each section is provided on one side with a groove H in which is seated a suitable packing I. The opposite side ofsaid section is provided with a tongue J. The sleeve isadapted to fit snugly at its ends around the feedpipe A and to prevent leakage at this point each section is provided with a seml-circular opening K in which are a pair of grooves havlng suitable packing L. One of these grooves, namely, the

innermost one is merely a continuation of H and the packing which the groove is preferably split longitudinally ofcharge opening,

likewise a continuation of With one of the sections seated therein is the packing I.

thus constructed, the other section is provided with its groove on from that of the groove the tongue J which carries the opposite side H,'in order that may abut against the packing 1t. In both sections the semicircular openings K are constructed alike,

that is to say, they are each provided with two grooves with packing. When the sections are joined together, the tongue and groove on one section is so arranged as to receive a grooveand tongue on the other section, and in this manner provide a tight joint. The device is further provided with a steam inlet opening such as M and an air discharge opening N. A suitable steam feed pipe 0 connects the steam inlet opening M for supplying the sleeve with the heating medium. Both the steam inlet opening and the air discharge opening are provided with raised flanges P which are formed on the inside of the sleeve, and in order to prevent flooding of the air dis charge opening when the device is in a horizontal position, a suitable discharge duct Q is provided in the flange of the steam inlet opening. This discharge duct extends transversely through the flange and is adapted to drain the device through the steam inlet opening. A suitable stop cock may be provided in the air discharge opening in order to control the discharge of air. When the evice is in a vertical position it will be drained through the steam inlet opening by means of the particular construction of the flange surrounding the steam inlet opening and when used in this position, the discharge duct merely carries off whatever moisture drips down the side wall of the section E.

I claim 1. A water heating device adapted to be attached to a feed pipe of a range boiler,

comprising a split sleeve, said sleeve having a steam inlet opening and an air dissaid openings being proflanges formed on the inside of the sleeve, and a transverse discharge duct provided in the flange of the steam inlet opening for draining the sleeve through said opening.

2. A water heating device adapted to be attached to a 'feed pipe of a range boiler comprising a split sleeve, said sleeve having a steam inlet opening and an air discharge vided with raised opening, said openings being arranged on the same side of the split sleeve and pro vided with raised flanges on the inside of the sleeve and a discharge duct provided in the raised flange of the steam inlet opening for draining the sleeve through said opening.

3. A Water heating device adapted to be attached to a feed pipe of a range boiler comprising a sleeve split longitudinnlly of the pipe to which it is to be attached, a steam inlet opening and an air discharge opening in said sleeve, said openings being provided With raised flanges formed on the inside of the sleeve and arranged in the same section of said sleeve, a discharge duct in the raised flange of the steam inlet opening for draining the sleeve through said opening, said sleeve embodying in its contlentet of thin patent may be attained for struction packing means comprising a tongue and groove provided on opposite sides of one section, suitable packing in said grooves; the tongue and groove on one section beingarranged to receive a groove and tongue on the other section when. the sections are joined together, and openings in said sections for receiving and surrounding the feed pipe of the boiler when the device is attached thereto, said openings having grooves Which are continuations 'oi the aforesaid grooves with suitable packing provided in said grooves, comprising a continuation of the packing provided in the grooves of one of said sections.
